If you are new in laravel 5 and you want to determine email is exist or not then you can do it easily. IF you did use code php then we have to write long code and check but laravel provide it's own query builder so it is pretty easy. you can see following example how i check row is exists or not:
<strong class="example">Example:</strong>
<pre class="prettyprint lang-php">
$user = User::where('email',Input::get('email'))->first();
if (is_null($user)) {
print_r("email is exists");
}
print_r("email is not exists");
</pre>

When you are working php or .net etc and you return data like json_encode($data) on ajax request. but in front side you get like a string at that time you have to parse json object and get them. so, let's see example and learn how to use:
<strong class="example">Example</strong>
<pre class="prettyprint lang-php">
var request = $.ajax({
type: 'POST',
dataType: 'json',
url: 'http://www.mysite.com/getpostuser',
data: {token:obj['token'],postid: obj['postid']}
});
request.done(function(msg) {
msg = JSON.parse(msg);
msg.forEach(function(items) {
var e = "notify-"+items.userid;
.....

Normally, we does use foreach loop in PHP, JS etc, but when i was working on socket programming at that time i require to use foreach of object in server.js. I did also search on google and try to how to use foreach in Node JS. At last i found to use forEach and solve it. so, let's see following example.
<strong >Example</strong>
<pre class="prettyprint lang-php">
socket.on("newmessage", function(obj) {
obj = JSON.parse(obj);
obj.forEach(function(items) {
console.log(items.userid);
var e = "notify-"+items.userid;
io.sockets.emit(e, 1);
});
});
</pre>
